Definitions

  • the invention relates to a spray cooler for regulating the temperature of superheated steam.
  • the spary cooler has a housing consisting of a housing head with a water inlet opening and a nozzle insertion pipe, and a nozzle head disposed at the end of the nozzle insertion pipe into the walls of which nozzles have been placed axially one behind the other.
  • An axially movable piston rod with a regulating piston on the nozzle end which controls the nozzles as a function of its position for unblocking or blocking the flow-through of cooling water is disposed inside the housing in a hollow-cylindrical cooling water line arranged between the water inlet opening and the nozzles. In in a closed position the regulating piston completely seals the nozzle head at the inlet side and in an open position unblocks all nozzles.
  • Spray coolers of the above mentioned type are known and are often used for temperature regulation of superheated steam, for example in power plants.
  • a spray cooler of the above described type is described in a pamphlet of the Narvik Armaturenvertriebsippo mbH Narvik Fitting Sales Company!, Erich Mullerstr. 22-24, 4000 Dusseldorf 13, Pamphlet No.: VN-A.T.-Temp-9002/08.
  • the known spray cooler cools superheated steam contained in a boiler or flowing in a steam line by injecting water which has been atomized by the nozzles.
  • the continuous amount of the cooling medium injected into the boiler or the steam line can be preset by a stroke setting of the regulating piston, wherein one or several of the nozzles are unblocked or blocked and the steam temperature of the released steam can be controlled in this way.
  • the stroke position of the regulating piston can be adjusted manually or can be controlled or regulated hydraulically or by an electric motor, in which case a temperature sensor introduced into the steam line transmits appropriate signals to a microprocessor controlling the stroke movements.
  • the known spray coolers have the disadvantage that often the nozzles are exposed to a very high feed pressure of the cooling water provided and are relatively rapidly worn or destroyed by this.
  • Pressure water lines under an operating pressure of more than 100 bar are often provided at the place where they are used.
  • the known spray coolers are used with a water pressure of sometimes more than 100 bar and the counterpressure of the steam to be cooled often is considerably less, so that almost the entire force of the water pressure is applied to the respectively open nozzles.
  • the nozzles are being destroyed relatively rapidly by erosion as a result of the flow speed. This causes, in addition to increased repair and replacement part costs, short maintenance intervals which increase the costs.
  • the object is attained in accordance with the invention in that at least one coaxial throttle area with an axially continuously widening throttle cross section is disposed on the piston rod between the water inlet opening and the nozzles, which is closed in the blocking position of the piston rod and which releases a largest possible ring-shaped throttle cross section in the open position.
  • the spray cooler in accordance with the invention advantageously utilizes the stroke travel of the regulating piston preset by the control of the nozzle sealing by means of the control pistons for achieving a pre-sealing of the cooling water line and a pressure pre-reduction at the respectively unblocked nozzles.
  • the pre-sealing throttle body which usually is a throttle cone, blocks the cooling water line in addition to the control pistons which block the water exit openings of the nozzles.
  • the pre-sealing piston unblocks the cooling water line in that upstream of the nozzles one cooling water admitting surface respectively matched to the opened nozzle surface is unblocked.
  • the cone-shaped design of the pre-sealing piston results in an increase of the cooling water admitting surface proportional to the stroke movement.
  • the cooling water admitting surface defined by the position of the pre-sealing cone reduces the pressure of the cooling water present at the water inlet opening to a degree which is designed for the nozzles and in this way reduces the wear on the nozzles caused by erosion.
  • the cooling water pressure is reduced in two stages in the novel spray cooler.
  • the first partial pressure reduction in this two-stage spray cooler takes place at the pre-sealing piston and the second partial pressure reduction in the nozzles.
  • the pre-sealing cone is advantageously disposed in the housing head.
  • nozzle insertion pipes of different lengths respectively the same housing head with the guidance receptacle in combination with the respective nozzle insertion pipe can therefore be used, because of which the storage and production costs are kept low.
  • a guidance receptacle which acts as a cone seat, in which the pre-sealing cone disposed on the piston rod is inserted, is advantageously screwed into the cooling water line.
  • This design permits the employment of particularly erosion-resistant materials for the guidance receptacle. Because of this the housing head can be made of a different, less expensive material.
  • the pressed-in guidance receptacle is preferably sealed steam-tight against the housing head.
  • the length of the pre-sealing cone corresponds to at least the stroke travel of the regulating piston.
  • the guidance of the pre-sealing piston in the outlet of the guidance receptacle on the nozzle side is assured by means of this. Because of its conical design, the pre-sealing piston is centered when the outlet on the nozzle side is closed, which assures the exact closing of the cooling water line in the closing stroke position.
  • the pre-sealing cone preferably has an expanded sealing collar on the outside of the guidance receptacle which, in the closing stroke position, additionally completely seals the guidance receptacle and thus the cooling water line on the outside of the outlet opening.
  • this expanded sealing collar assures a steam-tight blocking of the cooling water line in the closing stroke position and also is used as a stop for the closing stroke position.
  • the pre-sealing throttle body is advantageously designed to be conical or paraboloidal.
  • the curvature of the conical shape of the pre-sealing body which is determined by a parabola results in a more accurate adaptation of the cooling water admitting surface to the water outlet opening surface, while taking into consideration the flow and pressure conditions.
  • a three-stage spray cooler it has been provided to arrange two pre-sealing cones axially one behind the other on the regulating piston.
  • the two pre-sealing cones are assigned to respectively one guidance receptacle in the cooling water line, and in the closing stroke position block the respective guidance receptacle and therefore the cooling water line in a steam-tight manner.
  • This design of the spray cooler reduces the cooling water pressure at the water inlet opening in two additional stages, so that the reduced remaining pressure is present at the nozzles.
  • the cooling water pressure is reduced in a first stage at the first pre-sealing cone and reduced in a second stage at the second pre-sealing cone, because of which it is also possible to use a particularly high cooling water pressure present at the water inlet opening for cooling the steam without resulting in damage to the nozzles which represent the third pressure reduction stage.
  • the two cone seats disposed one behind the other are embodied in a guidance receptacle made of a flow-resistant material screwed into the cooling water line.
  • the guidance receptacle with two cone seats is sealed steam-tight against the housing head by means of a sealing ring.
  • the lower pre-sealing cone advantageously has an expanded sealing collar on the outside of the guidance receptacle which, in the closing stroke position, additionally seals the guidance receptacle and thus the cooling water line at the outlet side and is used as closing stroke position stop.
  • the spray cooler in accordance with the invention can be used without damage of the nozzles even at high cooling water pressures, since the pre-sealing cone(s) reduce the water pressure to a sufficient degree prior to reaching the nozzles.
  • a cooling water pressure of, for example, 85 bar is reduced by 30 bar by means of the pre-sealing cone in accordance with the invention.
  • a remaining pressure of 45 bar is present at the nozzles which, on the one hand, does not damage the nozzles and, on the other, is still sufficiently high to cause atomization of the water in the nozzles sufficient for steam cooling.
  • a cooling water pressure of, for example, 115 bar is reduced by the first pre-sealing cone by 30 bar and by the further pre-sealing cone also by 30 bar.
  • a remaining pressure of 45 bar is present at the nozzles which, on the one hand, does not damage the nozzles and, on the other, is still sufficiently high to cause atomization of the water in the nozzles sufficient for steam cooling.

  • the pre-sealing cone (12) opens the cooling water line (9) to the nozzle head chamber (7) in a manner matched to the unblocking of the water outlet opening (8) by the piston (11), by means of which a first pressure reduction stage is created ahead of the nozzles (8), which assures an almost constant water pressure at the nozzles (8) independently of the degree of unblocking of the nozzles.
